Stroke Volume Variation (SVV): Predicting Fluid Responsiveness in Critically Ill Patients
I have covered many things on this page, including resuscitation and fluid responsiveness.

This post will discuss stroke volume variation (SVV) and how it predicts fluid …
50000 Strong!

Central Venous Pressure (CVP) in the ICU: Does it predict fluid responsiveness? Nope.
Dinosaurs still roam the earth, I know this. They are slowly and surely retiring, though. I trained in the days where Manny Rivers and the Surviving Sepsis Campaigns pushed for Early-Goal Directed Therapy were king. Hey, there was a reason why it was so successful, EGDT decreased in-hospital mortality from 46.5% to 30.5% in that …
IV Vitamin C in Sepsis with Thiamine and Hydrocortisone
This article is hot-off-the-press regarding vitamin C, thiamine and hydrocortisone in refractory septic shock. This regimen is known as HAT therapy in some corners of the world. It was actually published today, 5/5/20. It is NOT a randomized control trial but at least they went through the trouble of conducting a propensity matched, before-after, case …

You've heard all these fancy terms, mixed venous blood gas, ScvO2, SvO2, thrown around the ICU all the time. Here, I explain what they are. Regardless of whether you're a nurse, respiratory therapist, medical student, resident, or even a fellow, these terms may sometimes be quite confusing as everyone talks about them like, "duh, you're …
